Application filed February 23, 1910. Serial No. 545,504.

To all whom it may concern:

Be it known that I, FRANCIS Lnvn'r hirer, a subject of the King of Great Britain, residin at Birmingham, county of Warwick, England, have invented certain new and useful Improvements in Temporary Binders or Loose-Sheet Holders, for which i have obtained British Letters Patent No. 4,660 of 1909, filed February 25, 1909, and of which the following is a specification.

This invention relates to improvements in temporary binders or loose sheet holders.

The main objects of this invention are, First, to provide in a temporary hinder or loose sheet holder an improved adjusting mechanism. Second, to-provide in atomporary binder or ,loose sheet holder an improved cover structure. Third, to'provide in a temporary binder or loose sheet holderhaving a back piece, an improved supporting and adjusting means therefor.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

- I accomplish the objects of my invention by the devices and means described in the following specification.

The structure described constitutes one eflective embodiment of my invention. Other embodiments would be readily devised by those skilled in the art.

The invention is clearly defined and pointed out in the claims.

A structure constituting an effective and preferred embodiment of the features of my invention is clearly illustrated in the accom panying drawing, forming a part of this specification, in which:

Figure 1 is an inside plan view of a structure embodying the features of my invention, the cover being shown open or extended, and portions broken away to better show the structural details. Fig. 2 is a central longitudinal section, parts being shown in dotted lines to better show their arrangement. Fig. 3 is a transverse section taken on a line corresponding; to the irregular line 33 of Fig. 2. Fig. 4: is an enlargeddetail through the adjusting mechanism, taken on a line corresponding to line 4-4 of Fig. 1. Fig. 5 is a detail section taken on a line corresponding to line of Fig. 4. Fig. (l is a detail section taken on a line correspondin to line (w-C of Fig. 5. Fig. 7 is a detail section taken on a line corresponding to line 77 of Fig. 5. Fig. 8 is an inverted- In the drawings, similar reference characters refer to simllar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawings, the covers 1. are preferably formed with chambers therein to receive the adjusting mechanism of the binder. The covers preferably comprise an outer wall 2 and an inner wall 3. At the inner ends of the covers are cover bars 4, which are secured to the inner walls of the covers, as by'means of the screws 5. These bars are also preferably provided with arms 6, which extend into the cover chambers, and are secured to the inner walls thereof, as by means of the screws 7.

An outer facing or covering 8 is provided in the structure illustrated. The cover bars 4 are, in the structure illustrated, provided with knuckles 9, which engage the groovelike sockets 10 in the outer faces of the clamping bars 11. These clamping bars are pivotally secured by means of the pintles 12. These pintles are preferably forfned of wire bent into the form of links, the wire being arranged through the knuckles and through the holes 13 in the clamping bars and their ends 14 folded down into the grooves 15 provided therefor in the inner faces of the clamping bars. The clamping bars are provided with holes or openings 16 for the binding cords 17, (see Fig. 11).

I preferably provide, in this connection, clamping strips 18 through which'the binding cords are arranged, the clamping strips being disposed on the inner si es of the clamping bars to prevent the leaves or sheets entering the grooves 15. The binding cords are secured at one end to the cover bar of one cover by means of rivets (see Figs. 1 and 10) and are adjustably connected to the other cover. This adjusting mechanism, in the structure illustrated, comprises a pair of facing ratchet bars v19, which are secured at their inner ends-t0 the cover bar 4. On these ratchet bars is slidably mounted a member 20 to which the binding cords are secured. This member is adjusted on the ratchet bars" by means of the pawls 21, which are pivoted at. 22 to the head ot' the adjusting lever 24. The pivots 22 are arranged on opposite sides of thepivot center of the head '23, so that they are alternately actuated as the lever is reciprocated. lhe lever i l is mounted on the binding cord member 20.

The pawls 21 are faced oppositely and held yieldingly into engagement with the rack or ratchet bars 19 by means of the spring -5, which is arranged between them.

"The pawls are preferably provided with lugs 26, with which the ends of the spring are engaged. This spring yieldingly holds the pawls in engagement, as stated, and per mits the free movement thereof without danger or liability of being displaced.

The ends of the paw-ls are preferably turned up to provide stops 27, which engage the shoulder-like steps 28 on the binding cord member 20, thereby limiting the actuating movement of the pawls. To disengage the pawls simultaneously when it is desired to open the mechanism to permit the removal of sheets or leaves, I provide a trip or pawl release 29, whichis mounted on the pivot 30 on the binding cord member, the member being provided with upturned flanges 31 to form supports for the pivot. This trip or pawl release is provided with upwaidly-projecting wedge-like fingers 32, which simultaneously engage the pawls when the trip is thrown upwardly, withdrawing them from the ratchet bars so that the binding cord member can be shifted freely.

The pawls are preferably provided with longitudinal slots 33, adapted to receive these trip fingers A finger piece 34 is provided for actuating this trip, the finger piece being adapted to be manipulated through the slot in the inner chamber wall. The pivot 30 for the pawl trip or release member 20 is preferably formed integ(1)a)lly with this finger piece 34. (See Fig. The trip 29 is provided with a stop or rest 36 for the finger piece 34, so that the finger piece has-some movement independently of the trip or release, and may be folded down, as shown in Fig. 1. When the finger piece is in its elevated position, pressure thereon throws the trip or release into engagement with the pawls, and after the pawls are disengaged, the finger piece serves as an opening finger piece. I have also preferably provided a closing finger piece 37, which ismounted on the pivot 38 carried by the flanges 31 on the binding cord member. This finger piece is preferably provided with a. spring 39 for normally retaining it in its collapsed position. The spring, in the structure shown, is in the form of a coiled spring arranged about the pivot 88, one end being connected to the finger piece and the other to the lever. In manipulating the binder, both the finger pieces may be grasped between the thumb and finger and the binding cord moved freely back and forth upon the ratchet bars. In closing the binder, the binding cords are drawn up as tight as convenient by means of the finger pieces and the lever 2st manipulated to actuate the pawls, which will place the binding cords under the desired tension. T hispro vidcs a mechanism which may be very quickly adjusted to permit the insertion or removal of sheets or leaves. I preferably, in this connection, provide a back strip 40, which is connected at one end to the binding member 20 to telescope into the chamber cover. The other end of the binding strip is adapted to telescope into the other cover, and is 'ieldingly supported thereon by means of a rod 41 which is carried by the cover member 4, and a member 42 which is slidably mounted on the rod and held yieldingly outward by means of the coiled spring 43 arranged upon the rod. The member 42 is connected to the end of the back strip by means of the straps l t. preferably formed of sheet metal so that the connection serves as a guide and prevents, to a large extent, lateral motion of the back strip which might result in its getting out of alinement.

I have illustrated and described my improved temporary' hinder or loose sheet holder in detail in the form in which I have embodied it in practice, and which I find to be a satisfactory embodiment. I am, however, aware that it is capable of considerable variation in structural details without departing from my invention, but as these variations will, no doubt, be obvious to those skilled in the art to which this invention relates, I do not attempt to illustrate or describe the same herein. but I desire to be understood as claiming my invention specifically in the form illustrated, as well as broadly within the scope of the ap pended claims.
